wechat-mp-sdk 0.3.0

//! Template Message Management API
//!
//! Provides APIs for managing WeChat Mini Program template messages.
//! Delegates to [`super::subscribe::SubscribeApi`] for the underlying implementation.
//!
//! # Features
//!
//! - Add templates from template library
//! - Get template list
//! - Delete templates
//! - Get category list
//!
//! # Example
//!
//! ```no_run
//! # use std::sync::Arc;
//! # use wechat_mp_sdk::api::template::TemplateApi;
//! # use wechat_mp_sdk::api::WechatContext;
//! # use wechat_mp_sdk::client::WechatClient;
//! # use wechat_mp_sdk::token::TokenManager;
//! # use wechat_mp_sdk::types::{AppId, AppSecret};
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! # let client = Arc::new(WechatClient::builder()
//! #     .appid(AppId::new("wx1234567890abcdef")?)
//! #     .secret(AppSecret::new("test_secret")?)
//! #     .build()?);
//! # let token_manager = Arc::new(TokenManager::new((*client).clone()));
//! # let context = Arc::new(WechatContext::new(client, token_manager));
//! let template_api = TemplateApi::new(context);
//!
//! // Get template list
//! let templates = template_api.get_template_list().await?;
//! for tmpl in templates {
//!     println!("Template: {} - {}", tmpl.private_template_id, tmpl.title);
//! }
//! # Ok(())
//! # }
//! ```
